Be it known that WILLIAM Caoss, a citizen of the United States, residing at Polo,

in the county of Ogle has inventedV certain and State of Illinois, new and usefu Iniprovements in Boxv Fasteners, of which the following is 'a specification.

This invention relates to box fasteners and is adapted primarily vfor use on egg cases when it is neces sary to have a secure fastening means vforthe lid or top cover.

The principal Vobject is to provide an e'icientspring fastener for use on egg crates and similar articles but which may be applied to various uses Another object of tl vide a fastener in trade.V ie invention is to proof the above mentioned character, which can readily and quickly be engaged and disengaged from the hd or' top.

A still further obje to provide a box fast described, which is si ct ofthe invention is ener of the character `nople in construction,

inexpensive, strong, durable and well adapted for the purposes mentioned. Y

Other objects and advantages Will become apparent during the course. of the following description.

case showing my improved lower portion of the andr Ll; show details of the latch Referring to the drawing in which siin'ilar reference charactersl designate correspending parts throughout the several cleats being adapted to rest upon the cleats 4: when the lid is in position, as shown in Fig. 1. In the drawing lI have shown a fragmentary view of the crate wherein only one end is disclosed, but it will be under-y stood that while reference is made to but one end of the crate, the o similarly constructed.

pposite end thereof is I provide a new and novel means for removably securing the lid in position on the crate and to this end ametallic plate 5 is provided, said plate being of elongated rectangular design and having its lower edge at the ends thereof formed with inwardly bent tongues or extensions 5', said tongues or extensions having the ends thereof curved or bent, as clearly shown in Fig. 2 of the drawing, the purpose thereof being herein- Vadjacent its endsand has the one leg portion thereof bent outwardly7 and the free end ll thereof engaged with the outer face of theplate 5, as shown in Fig. 1 of the drawing. The opposite end of the spring 8 designated as 12 contacts with the'end wall of the crate. The tendency of this spring obviously is to force the plate 5 inwardly against the cleats.

The cleat 3 is provided with a longitudi-v nal groove 15 formed in the outer face thereof and the upper edge of the plate 5 is bent at right angles to form a flange 16 which is adapted to be received in the'groove 15 when said plate 5 is properly acted upon by the springs 8. In this manner it is obvious wherein the lid or top 2 may be removably secured in position on the'box when the upper edge of the plate 5 is properly engaged with the groove and the cleat In order to prevent lateral movement of the lid or top on the box when engaged by the Yplate 5, the cleat 3 is provided with a staple.

17 within the groove 1.5 while the iiange 1G of the plate 5 is provided with a notch 1S to receive vsaid staple.

From the foregoing description of the.

construction of my improved apparatus, it will be seen that I have provided a simple, inexpensive and eilicient means for carrying out the objects of the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in forni, proportion, and in the minor details of construction may be yresorted to,

without departing froin the spirit or sacrificing any of the principles of the invention.

IVhat I claiin is l. In combination with a crate provided with a cleat on its end wall below the top thereof and a lid therefor provided with a depending cleat adapted to rest on the tiret mentioned cleat, the cleat on said lid being provided with a longitudinal groove in its outer face; of a plate pivotalljv7 carried on said crate and provided with an inwardly projecting flange adapted to he received in the groove of the last mentioned cleat., and spring means to nernrallgv retain said locking plate in engaging position.

In combination with a crate provided with a cleat on its end w ll loelow the top thereof and a lid therefor provided with a depending cleat adapted to vrest on the tiret mentioned cleat, the cleat on said lid heing provided with a longitudinal groeve in its outer face; ot a plate pivotally carried on said crate and provided with an inwardly `orojccting ,tange adapted to he received in the groove of the last mentioned cleat, and

nieans for preventing lateral movement of the lid with respect to Said locking plate.

3. In combination with al crate provided with a cleat on its end wall below the top thereof and a lid therefor provided with a depending cleat adapted to rest on the iii-st mentioned cleat, the cleat on said lid being provided with a longitudinal groove in its outer face; of a transverse rod extending across the end of said crate below the cleat` thereon, a locking plate pivotally carried on said rod and having its upper edge providcd with an inwardly projecting flange adapted for reception in the groove of the cleat on said lid, spring ineans in connection with said plate to nor1nall7 retain the latter in e'li'eetive engaging position, and means in connection with said plate and lid to preventlateral inovenient of the latter with respeet to the crate when the locking plate -i WILLIA M @R09
